PRINCIPLES OF MODERNIZATION Radar features automatic tracking capability as well as data receiving from other radar sensors. Data can be transferred over variety of communication channels. Radar transmitter and receiver feature solid state components only. Transmitter has modular design and provides ‘soft-failure’ redundancy: failure of individual module leads to partial performance degradation. Parameters of transmitted signal as well as parameters of signal processing after reception can be set at the operator workstation, secondary processing and tracking are performed at remote workstation. Remote workstation can be positioned in a Control Tower. ASR-22/AL can be remotely controlled from Tower. ASR-22/AL is intended for 24/7/365 operations and is equipped with UPS guaranteeing 10 minutes of operational time in case of mains failure. All air situation is automatically recorded with playback capability in passive and interactive modes.

COMPOSITION ASR-22/AL is structurally divided into two parts and consists of equipment shelter and antenna-feed system with rotary support connected by set of cables.

JAMMING AND INTERFERENCE PROTECTION ASR-22/AL features effi cient protection against pulse interference and active jamming. Level of interference is continuously monitored and graphically represented to the operator. Jamming protection is achieved through expansion of the dynamic range of the signal processor and capability of electronic frequency agility. Passive interference is rejected through digital adaptive MTI and generation of clutter map.
